Description

Technical Field

[0001] The utility model relates to the technical field of recycled water reuse and water resource disinfection and utilization equipment, in particular to a modular new water tank with a contact disinfection function. Background Art

[0002] According to relevant national norms and standards, many fields of water use have clear regulations on the residual chlorine content in the water used, and water storage and chlorination disinfection are widely used. At present, conventional water tanks such as stainless steel or steel plate water tanks are often used as chlorination disinfection and water storage carriers for the used water bodies. Conventional water tanks have horizontal and vertical reinforcements inside, and the overall structure is hollow. The internal water flow is complicated, which is not conducive to the control of the effective contact time between the disinfectant and the water in the water body. There may be a large volume of water that is delivered to the user before the effective contact disinfection time is reached, which poses a great water quality safety hazard. Moreover, the uneven distribution of residual chlorine in conventional water tanks will make the amount of chlorination uncontrollable and the disinfectant wasteful. In addition, conventional water tanks are prone to scale accumulation and need to be cleaned manually more frequently. In addition, the sampling of water bodies in conventional water tanks is mostly manual, with a low degree of automation and a long time.

[0003] A Chinese utility model patent with announcement number CN218810922U provides a combined disinfection automatic control system, which includes an ozone disinfection unit, a chlorine disinfection unit and a PLC control subsystem, and optionally includes an ultraviolet disinfection unit; the ozone disinfection unit is connected to the chlorine disinfection unit, and optionally, the ozone disinfection unit, the ultraviolet disinfection unit and the chlorine disinfection unit are connected in sequence; the PLC control subsystem is connected to the ozone disinfection unit, the ultraviolet disinfection unit and the chlorine disinfection unit respectively. Although the system can meet water quality indicators such as different chromaticity, pathogenic microorganisms and residual chlorine effluent, it also solves the problem that the amount of disinfectant added cannot be automatically adjusted according to changes in water quality and water volume during water treatment, effectively ensuring the disinfection effect and reducing operating costs. However, due to the design problem of the flow channel, the system may still have the situation where a large volume of water is delivered to the user before the effective contact disinfection time is reached, and there is a defect that the bottom of the box is easy to accumulate scale.

[0058] The liquid level meter 314 is installed on the box body, which is used to monitor the water level in the box body, and is preferably arranged on the water outlet module 3. The monitoring probe 51 of the water quality monitoring probe box 5 extends into the box body, which is used to detect the water quality in the box body, which is convenient for real-time monitoring. Preferably, the water quality monitoring probe box 5 is arranged on the water inlet module 1 and the water outlet module 3, and is preferably arranged on the sub-covers 111 / 311 of the two modules. The sampling control valve 702 is installed on the sampling tube 701, and the sampling tube 701 is connected to the box body, which is convenient for the staff to take samples regularly for testing. Preferably, the sampling control valve 702 and the end of the sampling tube 701 that is not connected to the box body are arranged in the sampling cabinet 7, and the sampling cabinet 7 is arranged at the water outlet module 3. The central control module is respectively connected to the liquid level meter 314, the water quality monitoring probe box 5, the sampling control valve 702, and the underflow propeller 120, so as to monitor and control the water tank through the central control module, realize the monitoring and control of the water quality, control and operation status of the water tank, and improve the automation of the water tank.

[0059] The water tank of the utility model is designed to be modular, and the number of intermediate modules 2 can be determined according to actual needs to meet the water disinfection requirements. After the number is determined, the modules are assembled and connected. During assembly, arc welding and other methods can be used for assembly and connection, and the external reinforcement channel steel 4 can be used for external connection reinforcement. Figure 1 and Figure 2 As shown. Since each module of the box has two flow chambers, and they are connected through the water passage 116 on the guide baffle 114, an S-shaped flow channel is formed inside the box, and water and disinfectant flow into the flow channel through the water inlet pipe 112, penetrate the entire box through the water passage 116, and then reach the water outlet pipe 312 of the water outlet module 3, and flow out from the water outlet pipe 312, so that the water is fully contacted and mixed with the disinfectant in the box, and when flowing, the water passes through the water passage 116 through the curved guide body 115 at the turning point, which better improves the water passing condition and avoids the local water backflow phenomenon near the water passage 116.

[0060] In the present utility model, the disinfectant flows in from the water inlet pipe 112. In order to better add the disinfectant, the water tank of the present embodiment also includes a supplementary chlorination module 8 for supplementing the agent.

[0061] Furthermore, the water inlet pipe 112 is preferably introduced into the water body from the top of the water inlet module 1 to the bottom, that is, the water inlet pipe 112 is arranged on the sub-cover 111 of the water inlet module 1, and is connected to the flow chamber of the water inlet module 1 from the sub-cover 111 downwards. Considering that the water body from top to bottom will impact the bottom of the box body, this embodiment is provided with an energy dissipation grid 113 in the water inlet module 1. The energy dissipation grid 113 is located directly below the end port of the water inlet pipe 112 connected to the water inlet module 1, and is spaced apart from the bottom of the module box 11 of the water inlet module 1, so as to reduce the impact of the incoming water flow on the bottom of the water tank through the setting of the energy dissipation grid 113.

[0062] In addition, the box cover is provided with an exhaust pipe 121 connected to the module box 11 / 21 / 31. Preferably, each flow chamber of each module is provided with an exhaust pipe 121. The exhaust pipe 121 is provided on the sub-cover 111 / 211 / 311 to discharge the gas generated in each module during the disinfection process through the exhaust pipe 121.

In addition, the water outlet module 3 is provided with a vent pipe 315, which is connected to the bottom of the module box 31 of the water outlet module 3; the water outlet module 3 is also provided with an overflow pipe 313. In order to facilitate inspection and maintenance, the water inlet module 1 is provided with an inspection manhole 117, an inner ladder 118, and an outer ladder 119. The inspection manhole 117 is located on the sub-cover 111 of the water inlet module 1, the inner ladder 118 is arranged on the inner side of the module box 11 of the water inlet module 1, and the outer ladder 119 is arranged on the outer side of the module box 11 of the water inlet module 1. The outer ladder 119 and the inner ladder 118 are both arranged at the location of the inspection manhole 117.

[0063] In addition, the central control module of the present invention is arranged on the operation status monitoring and control cabinet 6 , and the operation status monitoring and control cabinet 6 is preferably arranged outside the module box 11 of the water inlet module 1 and close to the outside ladder 119 . The central control module comprises a data collection and processing module, an operation status monitoring module and a control module, wherein the data collection and processing module is used to centrally collect data collected by various collection modules, such as the liquid level data collected by the liquid level meter 314, the water quality data collected by the water quality monitoring probe box 5, etc.; the operation status monitoring module is used to control the operation status of various valves, pumps and other equipment on the underflow propeller 120 and pipelines (such as the exhaust pipe 121, the reflux pipe 801, the water inlet pipe 112, the water outlet pipe 312, etc.), and has an operation status indicator light to obtain the equipment operation status through the indication of the operation status indicator light, such as, the indicator light is green to indicate that the equipment is operating normally, red to indicate that the equipment stops running, and flashing to indicate equipment failure, etc.; the control module is used to control the operation of the equipment and whether chlorination is added, such as controlling the opening and closing of valves, the start and stop of the underflow propeller 120, the start and stop of the pump, etc., or controlling the chlorination of the water inlet, the supplementary chlorination, etc.

[0064] Based on the above technical solution, the working principle of the utility model is as follows:

[0065] S1: Installation. Determine the number of intermediate modules 2 according to the scale of water treatment, assemble and weld the water inlet module 1, all intermediate modules 2 and the water outlet module 3, and install other components and line structures to obtain the following: Figure 1 The structure shown.

[0066] S2: Water tank operation. After closing the inspection manhole 117, open the water inlet valve and control the chlorination module 8 to operate. The disinfectant and the water enter the module box 11 of the water inlet module 1 through the water inlet pipe 112. The energy dissipation grid 113 dissipates the energy of the incoming water. The water flows through the flow channel inside the box under the action of the guide baffle 114 and the curved guide body 115, and finally is discharged to the outside of the box through the outlet pipe 312. In this process, the liquid level meter 314 with a sensor device feeds back the liquid level information to the central control module in real time. Based on this, the central control module starts and stops the pump, and issues an alarm in time when the alarm liquid level signal is reached, thereby controlling the water inlet of the box. When the water storage time in the box is long, the central control module controls the bottom flow propeller 120 to open in time to avoid the deposition of the bottom of the water tank.

[0067] S3: Chlorination and supplementary chlorination. The residual chlorine monitoring probe 51 in the water quality monitoring probe box 5 monitors the chlorine content of the water body near the inlet and outlet of the water tank, and the monitored data is fed back to the central control module. Chlorination is divided into water inlet chlorination and supplementary chlorination. Water inlet chlorination is the synchronous chlorination through the water inlet pipe 112 when the water tank is filled with water for a long time. When the water quality monitoring probe 51 detects that the residual chlorine in the water body has decayed to the set value, the central control module controls the control valve on the supplementary chlorination pipe 83 to open, the reflux pump 82 and the supplementary chlorination module 8 to operate, and supplementary chlorination is carried out through the reflux pipe 81. The added agent enters the water tank with the reflux water.

[0068] S4: Maintenance work. When it is necessary to enter the water tank for maintenance work, the maintenance manhole 117 is opened, and the manhole opening signal is transmitted to the central control module, which controls the closing of the valve of the water inlet pipe 112, the opening of the valve of the vent pipe 315, and the closing of the underflow propeller 120. After venting, the maintenance personnel start the maintenance work. If the maintenance manhole 117 is not closed normally, the valve of the water inlet pipe 112 cannot be opened.

[0069] S5: Real-time monitoring of equipment status. The probe 51 of the water quality monitoring probe box 5 is used as the monitoring probe 51 required by the water quality online monitoring device. It actually detects the water quality in the water tank in real time and sends the detection data to the central control module. The central control module determines the water disinfection status based on this, and then controls the water inlet, outlet and backflow of the water tank.

[0070] To sum up, the device provided by the utility model can achieve contact disinfection of water bodies, avoid local backflow of water carrying disinfectant inside the water tank, reduce agent loss, and effectively avoid sedimentation of the water tank bottom, reduce maintenance costs, and to a certain extent improve the operating safety factor of maintenance personnel. In addition, the water tank provided by the utility model can be modularly produced and installed, and has the advantages of short construction period and land saving.

In the process that the sampling storage box 904 rotates with the sampling rotating frame 903 and moves to the top of the rotation center line of the sampling rotating frame 903, the first limit baffle 909 on the sampling storage box 904 is gradually located Directly below the second limit baffle 910, the sliding drive rod 911 abuts against the inclined surface 912 on the sampling box cover 906 of the sampling storage box 904, and the sampling box cover 906 of the sampling storage box 904 slides to open the box opening 913 of the sampling box body 905 under the action of the sliding drive rod 911; when the sliding drive rod 911 slides and abuts against an end face of the sampling box cover 906 located on the outside of the sampling box body 905, the sampling box cover 906 opens the box opening 913 of the sampling box body 905, and the box opening 913 of the sampling box body 905 is located directly below the end of the sampling tube 701 that is not connected to the box body, and the first limit baffle 909 on the sampling box body 905 is located directly below the second limit baffle 910.

[0076] This embodiment of the utility model realizes the automation of sampling by setting up the sampling device 9 and the automatic control of the sampling control valve 702. In this embodiment, the sampling device 9 performs multiple timed sampling by setting up multiple sampling storage boxes 904. The multiple sampling storage boxes 904 face the sampling tube 701 one by one by rotating with the sampling rotating frame 903. Moreover, each sampling storage box 904 also uses rotation to realize opening and closing, so as to receive the sample flowing out of the sampling tube 701 and automatically seal after the sampling is completed, so that the whole process does not need manual operation and has a high degree of automation.

[0077] Specifically, each sampling storage box 904 is rotatably mounted on the sampling rotating frame 903 through the sampling box body 905, and the difference in gravity between the upper and lower sections allows the box mouth 913 of the sampling box body 905 to always be in an upward state, thereby preventing leakage of samples in the box body. At the same time, it is also beneficial for the sampling storage box 904 to rotate to the bottom of the sampling tube 701 (that is, directly above the central axis of the sampling rotating frame 903) so that the box mouth 913 can face upward, thereby facilitating sampling. Secondly, the box opening 913 of the sampling storage box 904 of the present embodiment is sealed by the sampling box cover 906, and the sampling box cover 906 uses a reset spring 908 to automatically close the box opening 913 of the sampling box body 905 without restriction, and can open the box opening 913 under force. In the utility model, the sampling box cover 906 is opened under force by the rotation of the sampling rotating frame 903, the end of the sampling box cover 906 extending out of the sampling box body 905 and the inclined surface 912 of the end, as well as the first limit baffle 909 on the sampling box body 905, the second limit baffle 910 on the sampling fixed frame 901 and the sliding drive rod 911. Specifically, the inclined surface 912 of the sampling box cover 906 is contacted and abutted by the sliding drive rod 911 during the rotation of the sampling rotating frame 903. Under the abutment force of the sliding drive rod 911, the sampling box cover 906 overcomes the elastic force of the reset spring 908 and slides on the sampling box body 905, and gradually opens the box opening 913 on the sampling box body 905 during the sliding process. When the sliding drive rod 911 abuts against an end surface of the sampling box cover 906 located on the outside of the sampling box body 905, the box opening 913 of the sampling box body 905 is completely opened. At this time, the sampling box body 905 moves to the bottom of the sampling tube 701 as the sampling rotating frame 903 rotates. By controlling the sampling rotation drive device 902 to stop, the sampling box body 905 can stably stay under the sampling tube 701, and then the opening of the sampling control valve 702 is controlled to achieve sampling. After sampling is completed, the sampling control valve 702 is controlled to be closed, and then the sampling rotary drive device 902 is controlled to operate, and the sampling box body 905 rotates with the sampling rotating frame 903. After the end surface of the sampling box cover 906 is separated from the sliding drive rod 911, the sampling box cover 906 is reset under the action of the reset spring 908, and the sampling box cover 906 covers the box opening 913 of the sampling box body 905, that is, the automatic closing of the sampling storage box 904 is realized. When sampling next time, the sampling rotating frame 903 rotates again until the next sampling storage box 904 is located directly below the sampling tube 701. The opening and closing of the sampling storage box 904 and the sampling process are the same as above. As long as the start and stop time and the running time of the sampling rotary drive device 902 are set, the opening time and the start and stop time of the sampling control valve 702 are matched, and automatic sampling can be realized.It should be noted that, in the process of opening the box mouth 913 of the sampling storage box 904, considering that the sampling storage box 904 and the sampling rotating frame 903 are rotationally connected, when the sliding drive rod 911 acts on the sampling box cover 906, it may cause the sampling box body 905 to tilt and flip. Therefore, a first limit baffle 909 and a second limit baffle 910 are provided. The second limit baffle 910 restricts the first limit baffle 909, so that the top of the first limit baffle 909 that enters the range directly below the second limit baffle 910 is restricted and cannot be flipped. In this way, combined with the gravity distribution method of the sampling box body 905, the box mouth 913 of the sampling box body 905 can always face upward.

[0078] Preferably, the first limiting baffle 909 and the second limiting baffle 910 are both arc-shaped plate structures, and the arc center is located on the rotation center line of the sampling rotating frame 903 .

[0079] In this embodiment, the sampling box cover 906 is provided with a through opening 907 at the end where the inclined surface 912 is located. When the sliding driving rod 911 abuts against the end of the sampling box cover 906, the through opening 907 is directly opposite to the box opening 913 of the sampling box body 905. When the through opening 907 at the end where the inclined surface 912 of the sampling box cover 906 is located extends out of the sampling box body 905, it is staggered with the box opening 913 of the sampling box body 905. That is, the opening and closing of the box opening 913 is achieved by whether the through opening 907 on the sampling box cover 906 is directly opposite to the box opening 913. The inclined surface 912 on the sampling box cover 906 can be provided on one side, such as Fig.16 As shown, both sides can also be set, such as Fig.17 As shown, the side walls of the sampling box cover 906 on both sides of the end extending out of the sampling box body 905 are both provided with inclined surfaces 912. In addition, the sampling device 9 is arranged in the sampling cabinet 7. The sampling rotation drive device 902 can drive the sampling rotating frame 903 to rotate by combining a rotating motor and a transmission assembly.

All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
